    led control with microcontroller

    I recommend you to divide your project in steps. 1 - Divide the 114 leds, i.e. in 6 groups of 19 leds 2 - make a controller board for the leds, this board must have 3 ports (8 + 8 + 3) of your microcontroller dedicated to activate the leds and a port pin for multiplex in time these 19 leds 3 -...

    how to make serial cable <-> RJ45 cable

    Yes you can. The simpliest way is to buy a wiznet board. http://wiznet.co.kr/Sub_Modules/kr/product/Product_Detail.asp?cate1=5&cate2=8&cate3=0&pid=1093 But i recomend you to buy these two modules for first test in the PC and then the microcontroller...

    what is meaning of sub netting

    We can divide the net in different small nets. The main idea of subnet is to manage efficiently the IP of the network so we can use the rights IP on all my net. Imagine this net 192.168.1.0/24. As you know the last char (0) means 256 hosts (2^8), the 24 means 24 1's of the netmask... 192...

    XBEE not communication

    You have to configurethe XBEE's on the same PAN and then program one like a coordinator (i.e.) and the other only change the Network address to 2, that's the easiest way

    generate triangular wave amplitude

    generate triangular wave If you are using an IC solution, you could simply add any n-bit DAC and step up to 2exp(n - 1) and then decrement... if not, using a R-2R ladder could help you, but i think you don't need feedback on the uC to generate this.

    Reading active energy with ADE7754

    Simplest way is S2 = P2 + Q2, where 2 means power of 2, S = apparent power, P=active power, Q=reactive power. Another way is integrating, is on a application note on analog devices.

    I need Spartan 3E XUP LabVIEW Driver for FPGA (8.5 version)

    National Instruments site only have drivers for 8.6 and 2009. The old 8.5 driver isn't on the page. I had found a forum that says is on the ftp, but link doesn't works. I saw the entire ftp and isn't there. I need the driver, please don't answer me with: "Ask a representative" or "Call NI"...
